The following investigation has caused us to wonder the following:
- How does DirectAdmin tally customer disk usage quotas?
- Additionally, how does DirectAdmin tally the email disk usage?
- Should customer IMAP directories be owned by root??
We have a customer on a server, which has a du that looks like this:
Code:
[root@server:~]# du -sm /home/customer /home/mysql/customer_db \
/var/spool/{mail/customer,virtual/customer_domains}
201 /home/customer
34 /home/mysql/customer_db
1 /var/spool/mail/customer
0 /var/spool/virtual/customer_domain_1
8 /var/spool/virtual/customer_domain_2
This would appear that
all disk usage tallies up to ~247MB. In the DirectAdmin web interface, the usage for this customer shows:
Code:
Total Disk Usage (meg) 247.6
Email Disk Usage 93.2 Mb
Database Disk Usage 32.1 Mb
Which makes sense on the surface. However, neither /home/customer/domains/customer_domain/stats or /home/customer/domains/customer_domain/logs are customer owned (root owned), so they would need to be removed from our estimate, I would think:
Code:
[root@server:~]# du -sm /home/customer/domains/customer_domain/{stats,logs}
3 /home/customer/domains/customer_domain/stats
17 /home/customer/domains/customer_domain/logs
Further, there are root owned IMAP files which attribute a massive chunk of the du as well:
Code:
[root@server:/home/customer/imap/customer_domain/user/mail]# ll
total 86260
-rw-rw---- 1 customer mail 515 Mar 17 2004 Drafts
-rw------- 1 root root 510 Mar 24 2004 INBOX.Drafts
-rw------- 1 root root 1352035 Jun 13 09:18 INBOX.Sent
-rw------- 1 root root 59751314 Jun 23 09:42 INBOX.Trash
-rw-rw---- 1 customer mail 27653 Mar 17 2004 Sent
-rw-rw---- 1 customer mail 27080691 Mar 17 2004 Trash
Using a find & tally command I wrote, I was able to discover that /home/customer only has ~116MB of actual customer owned files. See handy dandy oneliner:
Code:
t=0; for i in `find /home/customer -uid customer_uid -exec ls -ld {} \;|awk '{print $5}'`; \
do t=$[$t+i]; done; echo $t
(Note that the customer doesn't have very many files, so this works)
Naturally, one could also restrict find to only files, which would remove all the 4k directory counts as well, which would further lower the tally.
As a trouble shooting step, we tried setting the IMAP directories to customer ownership & re ran the tally, but that only skewed the disk usage even higher!
It is also worth mentioning that the email tally appears to be correct with or without the ownership of the IMAP files set (doesn't change, and appears to roughly match a du of /home/customer/imap, /home/customer/mail, /var/spool/mail/customer & /var/spool/virtual/customer/domains).
So, my questions, again, are:
- How does DirectAdmin tally customer disk usage quotas?
- Additionally, how does DirectAdmin tally the email disk usage?
- Should customer IMAP directories be owned by root??
